With Polk, you saw him for many years in the Pac‑10. He's obviously dropped a few pounds. So he looks a little differently from your camp. Same type of guy? Are you seeing similar attributes?
CHIP KELLY: Chris, yeah. I think in the last couple of days you've really seen Chris show up. He had a great practice when we were in the stadium. Hit a couple of nice runs today.
Really truly understands the blocking scheme, so he's patient in terms of understanding ‑‑ letting the blocks develop. But when he sees them, then sticking his foot in the ground and taking off. I think the last couple of days he's really come across.
I did see him in college. He was a workhorse for Washington. He was really the guy you had to stop. But he has versatility and can catch a ball coming out of the backfield. I think he's not just a one‑dimensional guy either.
